EXTRACTOR.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application led December 30, 1904. Serial No. 239,026.

To all lvl/0771j it '1n/fry concern:

Be it known that LVILLIAM HOLMES TEAS, a citizen of the United States, residing at Ridgway, in the county of Elk and State of Pennsylvania, have invented a new and useful Extractor, of which the following is a specification.

This invention relates to extraetors such as are employed in extracting woods, barks, leaves, twigs, berries, zc.

The objects of the invention are in a ready, rapid, and thoroughly practical manner to effect extraction of such substances, to provide means whereby the stronger extractions may be removed from the utensil as fast as produced without disturbing any of the parts thereof, to arrange the parts of the utensil in such manner as to permit of their ready removal for purpose of cleansing' or repair, and generally to improve utensils of the character described.

Vith the above and other objects in View, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of an extractor, as will be hereinafter fully described and claimed.

In the accompanying drawing, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

1n the drawing the ligure is a View in vertical longitudinal section through an extractor constructed in accordance with the present invention.

The extractor comprises a reservoir 1, an extractiiig-chamber Q, a holder 3 for containing the material to be extracted, and a dome or cover 4r for closing the upper portion of the extractor against escape of steam.

The reservoir may be made of any suitable material and is provided with a valve-controlled filling-spout 5 and with a neck 6, which is adapted to receive a plug or extension 7, formed on the bottom of the extracting-chamber and preferably integral therewith. The bottom 8 of the extracting-chamber is depressed or cone-shaped, and supported thereby at its perimeteris a perforated annulus 9, upon which rests the holder 3. The upper portion of the extracting-chamber is provided with a flange 10, the inner wall of which is slightly beveled and is engaged by an oppositely-beveled flange 11, carried by the dome 4 and by preference integral therewith, the joint thus formed being preferably secured by grinding the two flanges together, thus to secure an absolutely true and steam-tight junction. The dome is further provided with a marginal rim 12, which is separated from the upper edge of the flange 1() by a space 13, into which a suitable implement may be inserted for prizing the dome from the extracting-chamber, it being designed that the members shall be held assembled by frictional contact between the flanges 10 and 11. Secured to or integral with the under face of the dome isa collar 14, which, as shown, is approximately an inverted truncated cone` and supported by this collar isa foraminous or reticulated screen 15. Projecting' from the upper central portion of the dome is a tube 16, which leads to a suitable condenser (not shown) and for a purpose that will presently appear.

Rigidly secured to the bottom of the holder 3 are two tubes 17 and 1S, the former of which is the taller and is disposed centrally of the bottom and the latter being disposed adjacent to the inner wall of the holder. These tubes serve to support in proper operative position two siphons 19 and 20, the siphon 19 having' its longer leg projected through an orilice 21 in the plug T and its shorter leg' resting upon the bottom of the holder. The Siphon Q() is composed, preferably, of two members, one member 22 having its lower end resting upon the bottom of the holder and its upper end fitted within a second member i3, which projects upward through the tube 1S and has its lower end carried outward through the bottoni of the extracting-chamber and provided with a valve or cock 24E. The lower end of each ot' the members 19 and Q2 are beveled at and 26, thus to facilitate the free entry of liquid into the shorter legs of the siphons, as will be readily apparent. The siphon members 19 and 22 project through a foraminous or reticulated screen 2T, which is supported above the bottoni of the holder and operates to prevent the substance operated upon from being drawn into the siphons when the latter are in operation.

As stated, it is one of the objects of the in- IIO vention to facilitate cleansing of the interior parts of the apparatus, and to secure this result the Siphon 19 and the siphon 22 are de- Y-tachable from the holder, and the latter may also be bodily lifted from the extracting-chamber. In order to hold the Siphon 22 combined with its second member 23, the upper end of the latter member is provided with a tapered seat 28, which vis eng'aged by the tapered terminal 29 of the member 22, these joints being preferably ground to secure a perfect juncture between the parts.

In the operation of the device the holder is supplied with the material to be treated. rIhe dome is then secured in position, and water having been placed in the reservoir the latter has heat applied to it. AS soon as the steam is generated it passes up through the passage-,way 21 in the plug, thence through the orifices 8O of the annulus 9, and thence out through the condenser-tube 16, Where the vapors are condensed and again enter the extracting-chamber and are guided by the collar 14 into the holder. As soon as the level of the liquid or extract within the cup reaches the crest of the siphon 19 siphoning action immediately begins and the liquid is drawn from the holder and discharged back into the reservoir and the operation of filling the holder is again begun.

In some instance it is desirable to remove the iirst extract, as prolonged treatment of the material will tend to prove deleterious, and it is for this purpose that the second siphon is provided and is made shorter than the Siphon 19, so that when the cock 24C is open the first or strongest extract will be drawn from the holder and discharged through the cock 24 before the siphon 19 can beginits operation. Vhen all the stronger extract is removed, the cock 24 may be closed and the ordinary operation of the device will then continue as long as may be necessary.

It will be seen from the foregoing description that although the extractor of this invention is exceedingly simple of construction it combines in a ready and practical manner all the essentials necessary for the production of a thoroughly eective and serviceable apparatus, and, further, by the manner in which the parts are constructed that cleaning of the utensil may readily be eifected and that repairs in case of breakage may easily be accomplished.

6. An extractor comprising a reservoir, a normally sealed extracting-chamber, a holder disposed Within the extracting-chamber, a siphon communicating with the reservoir and with the holder, a second siphon communicating with the holder and discharging externally thereof, and means for controlling the passage of liquid through the second siphon.
